    利用奥维地图开展水土保持监测工作的方法

    Method of assisting soil and water conservation monitoring by using Ovitalmap

    • 摘要: 随着国家对水土保持监管工作的加强, 需要应用新的技术手段提高水土保持监测的效率和精度, 来满足新时期行业主管部门对该项工作的要求。利用奥维地图、CAD、ArcGIS软件和加载奥维地图的移动终端开展生产建设项目水土保持监测, 其便捷之处在于: 项目区水土流失本底值调查中可快速定位监测点位, 施工期可提前判定施工过程中易发生水土流失的区域, 日常水土保持监测工作中可有序记录监测数据, 制作扰动地表面积专题图件, 计算监测范围内的土壤流失量。行业主管部门通过上报的监测数据, 可实时查看管辖范围内建设项目的水土流失现状, 提前部署水土流失危害事件应急响应措施, 核查建设单位水土保持措施落实情况等。借助该方法可逐步实现多种专题的"一张图"管理, 减少水土流失, 达到水土保持监测数据共享化、主管部门监管方式多元化、群众参与渠道开放化的目的。奥维地图的部分功能需要用户支付费用, 且地图的地理要素属性数据统计汇总和叠加分析功能较弱, 建议进行优化。

       

      Abstract:
      Background Surface disturbance caused by production and construction projects is the main source of soil and water loss caused by human activities. In China, 25, 000 to 30, 000 soil and water conservation projects are approved every year. The competent departments of the industry mainly obtain the relevant information of the projects through paper reports, and the supervision tasks are large and the monitoring data acquisition lags. The purpose of this study is to use new technical means to assist the monitoring of soil and water conservation, improve the efficiency of supervision and management of soil and water loss in projects and the accuracy of monitoring data, and reduce the soil and water loss caused by man-made construction activities.
      Methods In this study, Ovital map, CAD, ArcGIS software and mobile terminals loaded with Ovitalmap were used to carry out soil and water conservation monitoring for production and construction projects. The technical path was divided into four aspects, which are the project area soil erosion background investigation, soil and water conservation monitoring during the construction period, daily monitoring data management, water and soil erosion hazards emergency response.
      Results Compared with no Ovital map, this method: 1) improved the accuracy of soil and water loss background survey data in the project area, and the data could be shared with other members in real time to carry out related work simultaneously; 2) it can quickly anticipate the area prone to soil and water loss in the construction process, so as to facilitate monitoring and improve work efficiency and monitoring results accuracy; 3) Ovitalmap, as data reported to management platform, facilitates the competent departments to carry out daily supervision and management; 4) Using maps to verify remote sensing results can improve the disposal efficiency of soil erosion hazards.
      Conclusions The use of Ovitalmap to assist soil and water conservation monitoring is beneficial to quickly and accurately obtain soil and water conservation monitoring data of production and construction projects, to improve work efficiency and data accuracy, and gradually realize the "one map" management of various topics with the help of this method, to provide diversified supervision and verification methods for the supervision of industry authorities, and provide an open participation platform for the masses to participate in and supervise the soil erosion of projects. Finally, it can improve the efficiency of supervision and management of soil and water loss in production and construction projects and reduce soil and water loss. Some functions of Ovitalmap require users to pay fees, and the map has weak statistical summary and overlay analysis of geographical factor attribute data, so it is recommended to optimize.
